Flutter 行的位置有问题

我正在为应用程序构建一个小部件。我在设置行的位置时遇到问题

我不知道如何设置两个图标按钮的位置，其中是黑色矩形。 我尝试使用main/crossAxisAlignment，但我只能得到行从中心向右移动的结果。 这是我的密码：

class CustomCardDetail extends StatelessWidget {
  CustomCardDetail({
    this.containerHeight,
    this.containerWidth,
    @required this.image,
    this.backgroundColor,
    this.colorTitle,
    @required this.title,
    this.titleFontSize,
    this.titleFontFamily,
    this.titleFontWeight,
    @required this.content,
    this.contentColor,
    this.contentFontSize,
    this.contentFontFamily,
    this.contentFontWeight,
    @required this.onPressedFavoriteButton,
    @required this.onPressedShareButton,
  });

  final double containerHeight, containerWidth, titleFontSize, contentFontSize;
  final String image, title, titleFontFamily, content, contentFontFamily;
  final Color backgroundColor, colorTitle, contentColor;
  final FontWeight titleFontWeight, contentFontWeight;
  final Function onPressedFavoriteButton, onPressedShareButton;

  @override
  Widget build(BuildContext context) {
    return Container(
      height: containerHeight,
      width: containerWidth,
      color: backgroundColor,
      child: Column(
        mainAxisAlignment: MainAxisAlignment.start,
        children: [
          Container(
            child: Image(
              image: AssetImage(image),
            ),
          ),
          Padding(
            padding: EdgeInsets.all(15.0),
            child: Container(
              color: Colors.red,
              height: 170,
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.stretch,
                children: [
                  Text(
                    title == null ? 'TITLE' : title,
                    style: TextStyle(
                      color: colorTitle,
                      fontSize: titleFontSize,
                      fontFamily: titleFontFamily,
                      fontWeight: titleFontWeight,
                    ),
                  ),
                  Padding(
                    padding: EdgeInsets.only(top: 15.0),
                    child: Text(
                      content == null ? 'CONTENT' : content,
                      style: TextStyle(
                        color: contentColor,
                        fontSize: contentFontSize,
                        fontFamily: contentFontFamily,
                        fontWeight: contentFontWeight,
                      ),
                    ),
                  ),
                  Row(
                    mainAxisAlignment: MainAxisAlignment.end,
                    crossAxisAlignment: CrossAxisAlignment.end,
                    children: [
                      IconButton(
                        icon: Icon(
                          Icons.favorite_border,
                          color: Colors.white,
                        ),
                        onPressed: onPressedFavoriteButton,
                      ),
                      IconButton(
                        icon: Icon(
                          Icons.share_rounded,
                          color: Colors.white,
                        ),
                        onPressed: onPressedShareButton,
                      ),
                    ],
                  ),
                ],
              ),
            ),
          ),
        ],
      ),
    );
  }
}

谢谢您的帮助。

在填充和行之间添加间隔符

Column(
                mainAxisAlignment: MainAxisAlignment.start,
                children: [
                  Container(
                    child: Image(
                      image: AssetImage(image),
                    ),
                  ),
                  Padding(
                    padding: EdgeInsets.all(15.0),
